My plants started drooping 4-5 days ago. the roots look alright, a little browning but no rot that I can see. Water temp fluctuates from 66-68 (chiller). PPM is 190 using current culture veg a and b, coco called and hydroguard, PH is 5.8. The only thing I can think of is shock from rising water level? I was leaving for the weekend so I dumped 4 gallons into the system and I did notice them start to droop. That was on Friday, and they slowly kept dropping more and more. The roots aren't completely submerged but can they get shocked by the water level rising a few inches?
